Solve 7x-4 = 5x+15 for x

tatiyna

$\bf{Hey\ there!}$

$\bf{7x-4 = 5x+15}$

$\bf{\underline{Subtract}\ 5x\ from\ \ on \ both\ of\ your\ sides!\downarrow}$

$\bf{7x-4-5x=5x+15-5x}$

$\bf{2x-4=15}$

$\bf{\underline{Add}\ by\ 4\ on\ each\ of\ your\ sides!\downarrow}$

$\bf{2x-4+4=15+4}$

$\bf{Cancel:-4+4\ because\ it\ equals\ 0}$

$\bf{Keep:15+4\ because\ it\ helps\ us\ solve\ for\ your\ answer}$

$\bf{15+4=19}$

$\bf{2x=19}$

$\bf{\underline{Divide}\ by\ 2\ on\ your\ sides!\downarrow}$

$\bf\frac{2x}{2}=\frac{19}{2}}$

$\bf{Cancel:\frac{2x}{2}\ because\ that\ gives\ you\ 1}$

$\bf{Keep:\frac{19}{2}\ because\ it\ gives\ you\ the\ the\ value\ of\ x}$

$\boxed{\boxed{\bf{Answer:x=\frac{19}{2}}}}\checkmark$

$\bf{Good\ luck\ on\ your\ assignment\ and\ enjoy\ your\ day!}$

A business has $15,000 to spend on airline tickets to travel to a conference. It wants 27 of its employees to attend. The busine

marusya05 [52]

Answer:

The correct answer is :

D. 700x + 375y = 15,000

x + y = 27

Step-by-step explanation:

1. Let's review the information given to answer the question correctly:

Budget for airline tickets = US$ 15,000

Number of employees attending the conference = 27

Price of business-class ticket = US$ 700

Price of economy-class ticket = US$ 375

2. Let's create a system of equations that models how many of each type of ticket the business should purchase.

x = Number of employees flying business-class

y = Number of employees flying economy-class

x + y = 27 (Number of employees attending the conference)

700x + 375y = 15,000 (Cost of employees flying business plus cost of employees flying economy equal to budget for buying the airline tickets)
